Jensen output transformers allow manufacturers to guarantee trouble free operation of their products when customers incorporate them into complex audio systems. Transformer coupled outputs work equally well driving balanced or un-balanced inputs and do not suffer from the stability problems encountered when connecting active balanced integrated circuit line drivers to un-balanced inputs with long cables. This transformer is designed for ultra-high performance line output stages. Specially processed 80% nickel core alloy is used for lowest possible harmonic distortion of high level low frequency signals. For best performance, driving signals should be free of DC and source impedance kept as low as possible.
